Maneskootuk Island (also called Doctors Island) is in the eastern part of Rangeley Lake. In the western part there is a small group of islands collectively called South Bog Islands.
Rangeley Lake has a designated water landing zone for seaplanes (United States Aerodrome M57 – Rangeley Lake Seaplane Base). This is one of only a very few aerodromes in the world to be serviced by a GPS instrument approach aligned to a water aerodrome, as well as an NDB approach; almost all other instrument approaches are aligned to runways on land surfaces such as pavement, asphalt, gravel, or turf.[1]
